The Mediterranean phytogeographic department has been a part of the Garden from its founding. Stone oaks, olive trees, strawberry trees, Mediterranean palms and other ligneous species together with a number of other flowering plants have been planted in the “Italian Boulevard.”

The department occupies the northwestern part of the Garden, along the railway line and its environs. Bordering the Australian Department to the south and North American Department to the north, it is 5.07 ha in size.
